There’s a tremendous amount of materials development taking place now to protect and improve the performance of the modern solider. One of the materials being actively investigated isn’t new at all, however. It’s wool—the same material used by the Army of the Potomac in the 1860s. The Marine Corps temporarily banned the wearing of synthetic materials by combat troops after soldiers sustained serious burns from clothing that burned, and sometimes melted, fusing to skin. Short-term, soldiers shifted to all-aramid clothing, an expensive and uncomfortable solution. The Army Soldier Systems Center has been developing a family of woolen, flame-resistant woven and knitted fabrics to replace polyester and nylon. The American Sheep Industry Association and the American Wool Council developed two knit fabrics and one woven fabric that are flame retardant. The US Army is current considering a fabric that is a blend of 50 percent wool and 50 percent Nomex, a meta-aramid made by DuPont. Wool improves the comfort and reduces the cost. TenCate Southern Mills received a million dollar order from the US Army to provide Lenzing FR rayon, for the Defender M program in which a fabric with a camouflage print made from Lenzing FR and para-aramid or polyamide. Lenzing FR may also be paired with wool in another program under evaluation.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
